本文为大家分享了SQL Server使用row_number分页的实现方法,供大家参考,具体内容如下

1、首先是

select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1

生成带序号的集合

2、再查询该集合的 第 1  到第 5条数据

select * from
(select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp
where rowNumber between 1 and 5

完整的Sql语句

declare @pagesize int; declare @pageindex int; set @pagesize = 3

set @pageindex = 1; --第一页

select * from (select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp where rowNumber between (((@pageindex-1)*@pagesize)+1) and (@pageindex*@pagesize)

set @pageindex = 2; --第二页

select * from (select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp where rowNumber between (((@pageindex-1)*@pagesize)+1) and (@pageindex*@pagesize)

set @pageindex = 3; --第三页

select * from (select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp where rowNumber between (((@pageindex-1)*@pagesize)+1) and (@pageindex*@pagesize)

set @pageindex = 4;--第四页

select * from (select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp where rowNumber between (((@pageindex-1)*@pagesize)+1) and (@pageindex*@pagesize)

 下面我们来写个存储过程分页 

Alter Procedure PagePager

@TableName varchar(80),

@File varchar(1000),---

@Where varchar(500),---带and连接

@OrderFile varchar(100), -- 排序字段

@OrderType varchar(10),--asc:顺序,desc:倒序

@PageSize varchar(10), --

@PageIndex varchar(10) --

as

if(ISNULL(@OrderFile, '') = '')

begin

set @OrderFile = 'ID';

end

if(ISNULL(@OrderType,'') = '')

begin

set @OrderType = 'asc'

end

if(ISNULL(@File,'') = '')

begin

set @File = '*'

end

declare @select varchar(8000)

set @select = ' select ' + @File + ' from ( select *,ROW_NUMBER() over(order by ' + @OrderFile + ' '+ @OrderType + ') as ''rowNumber'' from ' + @TableName + ' where 1=1 ' + @Where + ' ) temp where rowNumber between (((' + @PageIndex + ' - 1) * ' + @PageSize + ')+1) and (' + @PageIndex + '*'+ @PageSize+')'
exec(@select)

以上就是本文的全部内容,希望对大家学习row_number分页有所帮助。
